Scrabble coasters

Saw this idea on Pinterest ages ago and have been meaning to try it ever since... but it's a real struggle to try and get enough scrabble letters together (that actually come from the same set) to build up enough words to make a set of coasters. Saying that, the cork backing wasn't easy to get hold of, even the hobbycraft staff didn't know that they stock cork in their stores!

  

Tried to stick to drinks themed words for the coasters, 4 letter drinks words are a challenge to come up with as well...word suggestions for the next set are very welcome and any ideas where to get scrabble tiles cheap or free also appreciated. Think I'll put out another wanted request on freegle see what I can find.
